Provided are a motor generator control system and a hybrid vehicle capable of suppressing the amount of charge of a battery due to regenerative braking when the battery is fully charged or nearly fully charged. A motor generator control system (1) is provided with: a second motor generator (MG2); a drive current control unit (3) that, on the basis of the drive currents (Iu, Iv) of the second motor generator, performs feedback control so that the drive torque (Tq) of the second motor generator becomes a target torque (Tq *); a current coordinate converter (12) that calculates a d-axis current value (Id) and a q-axis current value (Iq) on the basis of the drive current and outputs the d-axis current value and the q-axis current value to the drive current control unit; and a strong excitation control command unit (21) that, when strong excitation control is performed during regeneration, executes current consumption control in which the d-axis current value (Ida) and the q-axis current value (Iqa) are changed so that the drive torque becomes smaller than the target torque and feedback control is performed.

    提供能在蓄电池处于充满电或接近充满电的状态时抑制由再生制动产生的蓄电池的充电量的电动发电机控制系统及混合动力车辆。电动发电机控制系统(1)具备:第二电动发电机(MG2);驱动电流控制部(3),其基于第二电动发电机的驱动电流(Iu、Iv)进行反馈控制以使第二电动发电机的驱动转矩(Tq)变为目标转矩(Tq*);电流坐标变换器(12),其基于驱动电流算出d轴电流值(Id)和q轴电流值(Iq)并输出到驱动电流控制部;以及强励磁控制指令部(21),在再生时进行强励磁控制的情况下执行电流消耗控制,在该电流消耗控制中,变更d轴电流值(Ida)和q轴电流值(Iqa)以使驱动转矩比目标转矩小,并进行反馈控制。
